In general, the EOS of hard sphere gas is given by Eq. (REF ). There are many proposals for the compressibility factor \(Z(\rho )\)  [1]}, [2]}, [3]}, [4]}. Since the general form of \(Z(\rho )\)  is not known, we take the commonly used Henderson relation Eq. (REF ) for EOS Eq. (REF ) to solve the continuity Eqs. (REF )-().
